CHARLES HENRY LAW, OF FOREST HILL, NEW YORK.

Application filed July 26, 1919.

To all whom it nmg concern:

Be it known that I, Cinumns HENRY LAW, a citizen of the United States, residing at Forest. Hill, L. I, in the county of Queens, State of New York, have invented a new and useful Vault-Light, Skylight, or Floor- Light Construction, of which the following is a specification.

My present invention comprehends a novel construction of a vault light, skylight or floor light construction, and relates more particularly to a novel construction of a cup or holder which constructed in such a manner as to prevent leakage between the lens and the holder and between the holder and the concrete which surrounds the latter.

it further comprehends novel construction of a lens receiving cup provided near its bottom with an inner and an outer annular groove or gutter to prevent leakage of water through the vault light construction.

Other novel features of construction and advantage will hereinafter more clearly appear in the detailed description of the invention.

For the purpose of illustrating the invention, I have shown in the accompanying drawing a typical embodiment of it which in practice will give satisfactory and reliable results. it is, however, to be understood that this embodiment is typical only and that the various instrumentalities of which my invention consists can be variously ranged and organized and are not limited to the precise arrangement and organization as herein disclosed.

Figure 1 re oresents a sect-ion on line 11 hi 2, of a vaultlight, sky light or floor ht construction, embodying my invention. Fig. represents a top plan view of the section seen in Fig. l with one of the reinforcing bars omitted.

Similar numerals of reference indicate corresponding parts.

Referring to the drawings.

1 designates a vault light construction which is provided at its lower portion with the reinforcing bars 2 and 3, respectively, and disposed at an angle to each other. & designates the concrete which surrounds the lens receiving cups or holders 5, in which are positioned the lenses 6. The lenses 6 are secured within their cups or holders by means of cement 7 and each holder consists preferably of a cylindrical ring or annulus Specifica'tion of Letters Patent.

having at its bottom portion a laterally extended flange 8 which is provided in its top face with an outer annular groove or gutter 9 and an inner annular groove or gutter 10. The bottom face of the flange 8 at its outer portion is flattened as indicated at 11 and is then curved downwardly and upwardly to form the annular enlargement or beam 12 from which extends laterally an annular flange 13. It will be understood that in the constrcution of the vault light or sky light construction a suitable form or mold is provided to form the open ings 1d and to support the lens receiving cups or holders 5 which are preferably of cast metal.

When the concrete is poured into place it interlocks around the bottom flange 8 and fills the annular groove or gutter 9, so that leakage between the outer periphery of the lens receiving cup 5 and the mass of concrete through the construction is prevented. The cement 7 is placed around the lens 6 and fills the annular groove or gutter l0 and serves to raise the bottom of the lens above the flattened face 15 of the flange 8, sothat the lens is positioned above the bottom of the lens receiving cup 5 and is supported wholly by the cement.

By the provision of the annular gutter l0 leakage through the construction between the l ns and the lens receiving cup is prevented. It will be seen that the lens employed is a flat surfaced glass without tongues, shoulders or grooves and its bottom face is preferably provided with reflexes 16.

If, for any reason, it becomes necessary to remove lens, it will be apparent that this can be readily done by simply breaking out the old lens, removing the old cement 7 and cementing a new lens into proper position in the lens receiving cup. The lenses can be readily replaced by an unskilled workman and without necessitating the em ployment of any staging from beneath the construction to supportthe lenses during such operation.

It will now be apparent that I have de vised a novel and useful construction of a vault light, sky light or floor light construe tice satisfactory and reliable results, it is to be understood that such embodiment is susceptible of modification in various particulars without departing from the spirit or scope of the invention or sacrificing any of its advantages.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

1. As a new article of manufacture, a lens receiv'ing cup for a vault light construction, comprising a ring having at its bottom a laterally extending flange provided at its top face on opposite sides of the ring with gutters.

2. As a new rticle of manufacture, a lens receiving cup, comprising a lens surround ingbody portion having at its lower end a laterally extending flange provided on opposite sides of the body portion with an inner and an outer water tight gutter located in the top face of the flange, the inner gutter being adapted to receive the lens securing material and the outer gutter and the outer portion of the'fiange being adapted to interlock with the concrete in which the cup is embedded.

A vault light, sky light or floor light construction, comprehending a lens receiving cup embedded in reinforced concrete, said cup consisting of a lens surrounding body portion provided at its bottom with a laterally extending flange provided in its top face on opposite sides of such body portion with an inner and an outer gutter, a

lens within said cup; cementitious material between the juxtaposed walls of the lens and the cup, one of said gutters preventing leakage through the construction between the lens and the cup and the other of said gutters preventing leakage through the construction between the cup and the reinforced concrete.

4:. As a new article of manufacture, a lens receiving cup, comprising an annulus having in its bottom a laterally extending flange provided in its top face in proximity to the annulus with an inner and an outer gutter, the inner portion of said flange forming a bead having an inwardly extending annular portion.

5. A vault light, sky light or floor light construction, comprehending a lens receiving cup consisting of an annulus having a laterally extending flange at its bottom, the flange being provided in its top face with an inner and an outer water tight gutter, a lens within said cup having unobstructed wide walls, cementitious material between the juxtaposed walls of the lens. and the cup and extending into the inner gutter and supporting the bottom of the lens, and con crete embedding said cup and extending into the outer gutter and interlocked with said flange.
